Ear drum rupture: Your ear infection was accompanied by an effusion - a collection of fluid behind the membrane. That fluid gave you the sensation of being "blocked". Now the pressure has reach a point that the ear drum ruptured and now that effusion can drain. It's not an uncommon occurrence. Finish your antibiotics and follow-up with your primary care doc for re-eval to assess whether ENT referral is needed.
